An Indian Grammarian anecdote
Once an Indian grammarian saw an empty Bullock cart and asked, 'Where is the pravetā (driver) of this cart?' Hearing that the driver came closer and said, 'Sir, I am its prājitā (driver).

The grammarian said,"Your word prājitā for the driver is grammatically wrong. No such word from the root aj has been listed by Pāņini & other grammarian sages. Yes, root aj" is used for driving but the Śāstras on grammar does not speak of any word like prājitā deriving from it''.

According to the Śāstras the word for 'cart-driver' is pravetā & that is the word you should use."
The driver replied, "My lord, you know the Śāstras very well, there is no doubt about that, but you know nothing about popular usage.''

The driver said ''Language has its own words, its own tendencies and its own laws, apart from and independent of the laws regarding language laid down in the Śāstras.
